Prayerful waiting on God is indispensable to effective service. Like the time-out in a football game, it enables us to catch our breath and fix new strategy. As we wait for directions, the Lord frees us from the tyranny of the urgent. He shows us the truth about Himself, ourselves, and our tasks. He impresses on our minds the assignments He want us to undertake. The need itself is not the call; the call must come from the God who knows our limitation. 'The Lord pities those who fear Him. For He knows our frame; He remembers that we are dust' (Psalm 103:13-14). It is not God who loads us until we bend or crack with an ulcer, nervous breakdown, heart attack, or stroke. These come from our inner compulsions coupled with the pressure of circumstances.
